method for deceleration of a vehicle train and combination of vehicle pneumatic braking systems of a vehicle train

摘要

The invention relates to a method for decelerating a combination of vehicles with a towing vehicle and at least one towing vehicle with an anti-lock brake system and a combination of vehicle brake systems of a combination of vehicles. In order to improve the braking behavior of a vehicle combination, according to the invention, an electronic brake control unit (30) of the tractor vehicle brake system (3) is provided which detects a current deceleration value of the vehicle. current vehicle (z-ist) continuously compares the actual vehicle deceleration value (z-ist) with a maximum deceleration (z-max) and, in the event that the actual vehicle deceleration value (z-ist) reaches or exceeds the maximum deceleration (z-max), limits the brake pressure (p) and provides an information signal (45) to the respective electronic brake system (31) of each tow vehicle (6) representing at least a state information limitation item (46), wherein the respective electronic brake systems (31) of a trailer brake system (4) - detect the measurement signals (35) of revolution rate sensors (34) ) and, depending on the measurement signals (34), apply the pressure (pa) to the wheel brakes (13) by actuating the pressure control valves (27), - receives (52) the information signal (45) and determines a dynamic slip variable value (v, vra) representing the slip in detecting braking pressure limitation (44) on the towing vehicle (5) using the measuring signals (34) for each tow axle (11, 12), - compares (49) the variable slip values (v, vra) of all trailer axles (11, 12) together and close the inlet valves (32) of the respective pressure control valves (27) of at least one of these trailer axles (12) with the largest slippages in compared to a control axis (11) and the currently smaller slip.
